Figure 1 MRI appearance of microneurovascular muscle flap in a 38-year-old woman with congenital left-sided facial paralysis. Free muscle transfer with the gracilis was done 2 years before MRI. This flap has almost normal muscle structure (grade 1 in present study) and the patient's mimic function is good (mild dysfunction). (A) In an axial T2-weighted MR image and (B) in an oblique coronal T1-weighted MR image, the free muscle flap is indicated with a white arrow.

Figure 2 MRI appearance of microneurovascular muscle flap in a 54-year-old woman with left-sided facial paralysis after cranial base fracture. Free muscle transfer with the latissimus dorsi was done 10 years before MRI. This flap has a fatty appearance (grade 2 in present study) and patient's mimic function is quite good (mild dysfunction). (A) In an axial T2-weighted MR image and (B) in an oblique coronal T1-weighted MR image the free muscle flap is indicated with a white arrow.
